Issue

I created a EJBTimerservice application which needs to run in a clustered environment. I setup the cluster and have deployed this application successfully under the /deploy folder which successfully gets deployed.
I am now changing the structure so that the timer service runs under the deploy-HASingleton folder as we have 4 servers hosting the application. I need this service running on one machine only, so there is only one timer on the cluster.

The timer also needs to start when deployed. How do I acheive this?
